Published Tidal landscapes a greater carbon sink than previously thought
(via sciencedaily.com) Original source Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research shows that these environments are perhaps twice as effective as previously thought.
Published Physicists develop highly robust time crystal
(via sciencedaily.com) Original source Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.
Published Single proton illuminates perovskite nanocrystals-based transmissive thin scintillators
(via sciencedaily.com) Original source Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.
Published Short X-ray pulses reveal the source of light-induced ferroelectricity in SrTiO3
(via sciencedaily.com) Original source Researchers have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. They exposed the material to mid-infrared and terahertz frequency laser pulses and found that the fluctuations of its atomic positions are reduced under these conditions. This may explain why the dipolar structure is more ordered than in equilibrium and why the laser pulses induce a ferroelectric state in the material.
Published Scientists make breakthrough in quantum materials research
(via sciencedaily.com) Original source Researchers describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.
Published Floating algae a raft for juvenile pelagic fish
(via sciencedaily.com) Original source Floating macroalgal acts as a raft that provides habitat for a diverse array of juvenile oceanic fish a new study has found. The study conducted in the Ningaloo Coast World Heritage Area, Western Australia, revealed that fish were more abundant around macroalgal rafts than in open water, with eleven species of juvenile fishes associated with Sargassum rafts, and one species of both juveniles and adults.
Published As sea otters recolonize California estuary, they restore its degraded geology
(via sciencedaily.com) Original source As sea otters recolonize a California estuary, they are restoring its degraded geology by keeping populations of overgrazing marsh crabs in check, a new study shows. The crabs' appetite for plant roots, and their tunneling behavior had caused many of the estuary's marshes and creekbanks to erode and collapse in the otters' absence. Today, erosion has slowed by up to 90% in areas with large otter populations and marshes and streambeds are restabilizing.
Published Researchers craft new way to make high-temperature superconductors -- with a twist
(via sciencedaily.com) Original source An international team has developed a new method to make and manipulate a widely studied class of high-temperature superconductors. This technique should pave the way for the creation of unusual forms of superconductivity in previously unattainable materials.
Published A green alternative for treating Streptococcus iniae bacteria in hybrid striped bass
(via sciencedaily.com) Original source Scientists have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.
Published Superfluids could share characteristic with common fluids
(via sciencedaily.com) Original source Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow. The degree of laminar or turbulent flow is referred to as the Reynolds number, which is inversely proportional to the viscosity. However, this Reynolds similitude does not apply to quantum superfluids. A researcher has theorized a way to examine the Reynolds similitude in superfluids, which could demonstrate the existence of quantum viscosity in superfluids.
Published Scientists pull off quantum coup
(via sciencedaily.com) Original source Scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.
Published Endangered seabird shows surprising individual flexibility to adapt to climate change
(via sciencedaily.com) Original source New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought.
Published Use it or lose it: How seagrasses conquered the sea
(via sciencedaily.com) Original source Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.
Published Unexpected biodiversity on the ocean floor
(via sciencedaily.com) Original source Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Shining a light on the hidden properties of quantum materials
(via sciencedaily.com) Original source Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz time-domain spectroscopy, to learn more about a quantum material called Ta2NiSe5 (TNS).
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web
(via sciencedaily.com) Original source Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Humpback whales move daytime singing offshore
(via sciencedaily.com) Original source New research revealed a daily pattern wherein humpback whales move their singing away from shore throughout the day and return to the nearshore in the evening.
Published Researchers add a 'twist' to classical material design
(via sciencedaily.com) Original source Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.
Published What coffee with cream can teach us about quantum physics
(via sciencedaily.com) Original source A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
Published Gravity helps show strong force strength in the proton
(via sciencedaily.com) Original source New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.
